Specification of Letters Patent.

Patented Feb. 19, 1907.

To (LH whom, it 'W1/wy conce/nh- Be it known that we, FRANK ARTHUR BooLE and LEONARD DEE STEPi-r-ENsoN, citizens' of the United States, and residents of Blaine, in the county of Whatcom and State of Washington, have invented a new and Improved Car, of which the following is a full, clear, and exact description.

Our invention relates to cars, and es ecially to those for holding lumber in ki ns during process of drying. Its principal objects are to provide such a car in which each piece of lumber will be separated from those adjacent to it by an air-s ace and which may be readily assembled or isassembled.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate correspondin parts in all the iigures.

Figure 1 is an end e evation of one embodiment of our invention; Fig. 2 is a longitudinal section on the line 2 2 of Fig. 4. Fig. 3 is a side elevation of the car, and Fig. 4 is a' horizontal section on the line 4 4 of Fig. 1.

The numeral 10-indicates an ordinary dry- 4kiln truck, its wheels 11 being adapted to run upon rails, (indicated at 12.) Two or more of these trucks support a base consisting of beams 13, here shown as two in number and carrying sills 14, which may vary in number according to the length of the lumber to be supported, there being three here illustrated. Each of the sills is shown as reinforced upon its upper face by a channel-A iron 15.

Extending upwardly lfrom opposite sides of one extremity of each of the sills is a retaining member 16, and between these bars or retaining members is supported an upright, including a barl 17 having at its inner side a facing 18, furnished by a channel-iron. Straps 19, fixed to the retaining members, surround each upright to hold it in place upon its sill. In the inner face of each of the bars 17 is a vertical series of depressions 20, in re istration with which are openings 21 throug the channel-irons 18, these openings being at the upper portion of the depression and iurnishing at the lower portion a chamber closed save at its upper extremity. With these depressions and openings lcooperate hooked and engaging portions 22 of supportchannel-irons `having their anges extending downwardly. The engaging portion is of such width that each support is held against lateral movementv in the opening 2l, while the contact of the hooked end. which projects into the chamber, retains the support against longitudinal movement.

The supports beyond the uprights are separated from their sill and from one another by tubular spacing members 24, which may consist oi sections of pipel located between the ends of the elements and extending upwardly. They are shown as secured in place by bolts 25, the head 26 of each engaging the upper extremities lof the tubes, while the Shanks pass downwardly through openings inthe supports and are threaded to receive the nuts 27. The length of the member 24 is such that the supports are maintained in parallelism with one another at right angles to the uprights. each support and also the sills have tubular spacing members 28, plugged at 29. In the plug of each of these members is a bore to receive a bolt 30, which extends downwardly To sustain their outer ends,

through the support or sill and is secured by f a nut 31. The length of the plug is such that a recess is left at the upper extremity of the members 28. -When the elements are assembled this recess receives the head of the securing-bolt above it. -Thus the outer ends of the supports are held against lateral play. Rising from each sill and support between the upright and supporting members are series of projections 33, which may be furnished by sections of pipe of less diameter than the separating members,- secured in place by bolts 34 and nuts 35 in the same manner as has been described in connection with the members 24. The length of the projections 33 is preferably somewhat less than the separating members, so that spaces are left between them and the iianges of the supports.

In using our improved car a base is built up by employing the desired number of trucks, beams, and sills and uprights of such a length as to give the requisite holding capacity, applied as has been previously described. The supports, bearing the separating members and projections, are then placed one upon another until the car is completed. The pieces of lumber indicated at A may now 'be inserted between the separating members and projections and when thus placed are IOO entirely free from contact with one another, they being surrounded by a free air-space, save of over the widely-separated and (ontracted portions Whore' they contact with the supports and other extensions. When the car and its load is within the kiln, this arrangement insures a quite uniform drying, and by using slow heat at the start the perfect circulation secured `will a proximate airdrying, escaping the usua deterioration resent in kiln-drying. In addition it will e seen that the structure admits of being readily built up to meet the requirements of any particular case and as easily .knocked down for storing away or transportation.

Having thus described our invention, we claim as new and desire to secure by Letters Patent- 1. A car comprising a base, spaced uprights secured to one side of the base, a vertically-spaced series of supports detachably connected'wth each of the uprights, spacing members connected to the free end of each. support, and adapted to engage the overlying support, and a spacing' member for the free end of the lowest support secured to the base.

2. A car comprising a base, spaced uprights secured to one side of the base, a vertically-spaced series of supports detachably connected with each of the uprights, spacing members connected to theree end oi each support, and adapted to engage the overlying support, a spacing member for the free end of the lower support secured to the base and spaced projections upon each of the supports and upon the base, said projections being of less height than the spacing members.

3. A car comprising a base, spaced uprights secured to one side ofthe base, a vertically-spaced series of supports, detachably connected with each of the uprights, spacing members connected to the free end of each support, for Aengaging the overlying sup ort, a spacing member for the free end o the lower support secured to the base, and means in connection with the spacing members and sup orts for preventing lateral-movement of sal supports with respect to said spacing members.

4. A car comprising a base, spaced uprights secured to one side of the base, a vertically-spaced series of supports detachably connected with each of the uprights, spacing members connected with the supports, and a spacing member for the lower support connected with the base.

5. A car comprising a base, an upright having openings, supports provided with hooked portions for engagement with the upright-openings and means of separating supports at points removed from the uprights.

6. A car comprising a base, an upright, supports connected with the upright and having projections,v and tubular members fixed to the supports and having recesses for coperation with `the projections upon an adjacent support.

7. A car comprising a base, an upright, bar having depressions, a channel-iron situated at one side of the bar and having openings registering with the depressions, supports provided with portions cooperating with said openings. and depressions and also having series of projections.

In testimony whereof we have signed our names to this specification in the presence of two subscribing witnesses. l FRANK ARTHUR Boom.
